Preparations
Additional processing
When the [Sub Channel Settings] is set to ON, one of the following items
can be measured with main channel as simultaneous measurement function
(see page 80).
C-weighted equivalent continuous sound level
L
Ceq
C-weighted peak sound level
L
Cpeak
Z-weighted peak sound level
L
Zpeak
I-time-weighted equivalent continuous sound level
L
AIeq
Takt-max A-weighted sound level
L
Atm5
Maximum I-time-weighted equivalent continuous sound level
L
AImax
(When the optional Extended Function Program NX-42EX is not installed,
L
AIeq
and
L
AImax
cannot be measured.)
The frequency response of additional processing is associated with that
of sub channel. Therefore,
L
AIeq
or
L
AImax
can be selected when the sub
channel has A-weighting,
L
Ceq
or
L
Cpeak
can be selected when the sub
channel has C-weighting,
L
Zpeak
can be selected when the sub channel
has Z-weighting.
Note
If the additional processing value is not set to “ON”
on the display menu, measurement data of additional
processing is not stored.
